ANOTHER UPDATE
Miracle's bloodwork results came back. No significant organ issues, but his numbers are "off." We will see how that unfolds with time. He is heartworm negative, so that is huge! He LOVES to eat. He continues to do well, but he still has a long road ahead. For the 3-day weekend, he will go home with the vet tech, who is an IDR+ volunteer and adopter, so he will have 24-hour care.
He can lift his head, eat, and drink. And he pooped! That was a huge step. They "walk" him a few times a day to try to get him to walk for real.
It also appears as if he's got a fishhook and some fishing line in there - so he was probably so hungry he was scrounging for anything he could eat - maybe down by a river, where he found the fishing gear.
He's going home with "his" vet tech - an IDR+ volunteer and adopter - for the long weekend so he can have 24/7 care. All bundled up and ready to go!
